National bulletin – Weather situation and general development – Updated on Sat 05/30 – 5:42 p.m.
Multiplication of thunderstorms from the South from Monday
+ For the moment, the high pressures centered on Scandinavia are so vast that they maintain a stable and clear weather on 4 / 5ths of French territory (outside the Southeast quarter >>).
+ This will also be the case on Sunday, then the Scandinavian high will begin to weaken and then disappear.
+ As a result, France will be less protected – and from Monday, the thunderstorm risk will spread to the regions located south of the Loire (even if thunderstorm activity will remain limited and especially present in the Pyrenees).
+ Between Tuesday and Thursday, thunderstorms will increase but it is almost impossible to know exactly where they will break out during these three days. The risk will obviously be greater in the second half of the day and especially on the reliefs while the regions north of the Seine could be spared.
+ Friday: a flow of much cooler air will descend from Spitsbergen over the entire North Sea and will slowly arrive in the North of France over the next weekend.
The fall in temperatures will take place gradually, and the southern half will probably be affected in a second time.
